LS Turn Key Engines

We are passionate about building quality, high performance engines... and it shows.

Our engines can be seen in the race results and standings of such events as King of the Hammers, Best in the Desert, SCORE, W.E.ROCK, XORRA, TrophyLite and SNORE, where you will see an impressive number of drivers powered by a Turn Key engine.

On the streets, Turn Key engines can be found in award winners like the Good Guys Street Machine of the Year, built by Roadster Shop, and countless articles in hot-rod/restomod magazines like Super Chevy, Chevy High Performance and GM High-Tech Performance.

Turn Key Engine Supply is the industry leader in custom-built LS1, LS2, LS3, LS6, LS7 and Ecotec crate engines. Each engine features our patented 5 Wire Plug and Play Harness that includes a state-of-the-art Delphi ECM with Turn Key precision engineered calibration. The result is easy installation matched with incredible performance. We offer a comprehensive selection of engine packages from mild to wild, and can also build an engine designed especially for your needs.

A Turn Key engine arrives at your door completely assembled, tested and ready to drop in. Just connect five wires, fuel and water lines and you are ready to roll. What does that mean to you? Our studies have shown that a Turn Key engine package will save you countless hours. Imagine all the time you won't spend driving around looking for the right bolts, washers, gaskets, hoses and more.
